EDWIN E. SLICK, OF PITTSBURG, PENNSYLVANIA.

- EUTARY sHEARs.

To all 'whom it 'may concern:

Be it known that I, EDWIN E. Suck, of Pittsburg, Allegheny county,Pennsylvania, have invented a new and useful Rotary Shears, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of 'this specification, inwhichi Figure 1 is a plan view of rotary shears apparatus constructed inaccordance with my invention; Fig. 2 is a front elevation of the samepartly in section; and Fig. 3 is a side elevation, partly in sect-ion. l

My invention rela'tes to rotary shears, and particularly to the shearingof hot ingots or blooms of substantially cylindrical form.

The invention relates particularly to the forming of steel wheel blanksfrom a cast steel`ingo't, though it'may be employed for cutting off tireblanks or other blanks from a long cylindrical blank or section.

The object of the invention is to provide a simple, cheap andrapidly-operating device by which the blanks may be sheared from theingot, and if desired, partially shaped during the shearing action.

In the drawings, 2, 2 represent the rotary shear blades whiclraremounted on shafts 3, 3, the blades either being rotatably mounted on theshafts or being secured to the shafts which turn in suitable bearings.In either case, the rotary shear blades are positively rotated, thisbeing done in the form shown by wabblner connections e to pinions 5 and(i. driven from the intermediate pinion 7. The bearings for the rotaryshears are carried on 'SlidingcrOss-heads 8 moving on guides 9. Thecross-heads are moved toward or from each o'ther by hydraulic or otherfluid pressure cylinders 10, and kare drawn back by the .pull-backcylinders 11. In order to cause uniform travel of thetwo shear blades, Ipreferably connect the crossheads by links 12 and 13 with the oppositelyprojecting equalizing levers 14a and 14b sel cured on the pivot shaft.14. Other means,

however, may be employed for making 'the travel of the two shear bladesuniform, or such device may be done awayfwith entirely. l t

The ingot to be sheared is carried upon a suitable support which I haveshown as consist-ing of two rows of antifriction rollers 15, and anantifriction roller 16 between and below 'the two shear blades. 'Theingot lies upon these sets of rollers, and may be ad- Speceaton ofLetters Patent. Patented July 19, 1910.

justed forwardly by the pointed end 17 of a plunger 18 in the cylinder19 in line with the roller 16. j I

In the operation of the apparatus, the cylindrical ingot is Alaid on theantifric'tion rollers in substantially the -position shown inv dottedlines in I1`igs.-1 and 2. It is then shoved forward by the pointed endof the plunger 1S, so that i'ts front end projects upon the shears thedesired distance. The shears are then positively rotated, and .at thesame time simultaneously moved toward each other. They gradually enter'the sides of the ingotand cut a deepening annular groove therein, thefluid pressure cylinders 1() finally bringing the two shear bladestogethe'r, if this is desired. The operation may also be carried outwithout completely severing the blank, as the remaining neck or stemportion may afterward be cut away or ren'ioved, either by punching acentral hole inv the blank, or in any other desired way. After the blankis thus severed, 'the cutting disks are retracted, the ingot is adjustedforwardly to the proper distance, and the 0pof cutting off one blank,the'circular hub portion 2O of the shears acts upon the next blank tosize it before it is cut off, thus in the form shown, there is a sizingaction on one blank simultaneously with the cutting off of the otherblank ahead of it.

rThe ingot may be supported upon centers projecting into centering holesin its opposite ends. The shape of the shear blades may be varied so asto simply cut the blank, or to partially shape the blank being cut, orthe next blank being cutoff or both; and many other changes maybe madewithout departing from my invention.
